I had my first and only (so far) at home 20 months ago. It was a planned water birth at home in the middle of winter up in a mountain cabin. It was my parents' house, so they were already there. However, I was in the downstairs and they were upstairs. You have to walk outside to go between the two. I didn't even tell them I was in labor, but I think my husband did. Plus the midwife and doula showing up probably gave it away.
The cabin was at least 2 hours away from all our other family and friends with two closed roads up the mountain. There was a snow storm coming our way so we wanted to give them a good amount of warning to get here, but didn't want them waiting around for hours. We only invited our parents, my brothers and our two best friends (godmother and godfather). Total invited was 9 and 8 showed up (1 of my brothers didn't come).
Since it was our first pregnancy we were trusting the midwife to tell us when a good time was to call everyone. Around Noon my husband called everyone as I was in more active labor, but not yet pushing. I started pushing at 2:20 and she was out at 2:45 pm. My parents heard her cry through the floor, but didn't come down. They are very respectful of my space.
The first visitors were my FIL and his wife to show, quickly followed by the rest. Everyone was surprised that she was already born by the time they arrived. They all headed upstairs and hung out waiting for us to invite them down. Thankfully our families get along well.
Immediately after her birth my husband and I climbed into bed. I got her attached within the first 15 minutes. We relaxed and waited another 15-30 minutes before cutting the umbilical cord, then about 15 minutes later pushed out the placenta. My midwife started a bath for me so I could get cleaned up. Once dressed and in bed again my hubby got everyone from upstairs. It was probably an hour or two from her birth before they were invited down. Then we all guessed how much she weighed and everyone got to hold her.
We had plans and they went smoothly. I think it helped that it was in the middle of the day for everyone to show up. I really enjoyed it and didn't feel tired or stressed with everyone there. Everyone was supportive and calm. Actually many stayed all night and slept over as the snow storm hit. However, they didn't really overstay their welcome as they slept upstairs in my parents section of the house. It made it easier for each person to spend a few hours with us and the new baby. Many of them wouldn't be seeing her for a few weeks or months later so we were more open to them staying longer.
It was actually a very peaceful day.
(Sorry for the novel. Thought some back story was needed to understand the situation.)
